bopper punching bag

Most listings show an overall height of about 47 inches; a few list about 48 inches — generally around 47–48 inches.

They are typically listed as made from PVC (polyvinyl chloride). Some listings use the more generic term “plastic.”

Manufacturers instruct filling the base with at least 2.5 kg of water to stabilize the bopper, then inflating the body with an air pump.

Bounce-back action comes from the weighted base reacting to impacts so the bopper quickly rebounds after being hit.

Drain the water from the base outlet, then fold the body and store it compactly.

Some versions include an air pump for inflation and a belt for hanging; reviews also note that some products include a repair patch for minor leaks.
